a To all whom-imag concern; 4 A Be itz-known that I, M'IQHAELB..` GREENa citizen lof. the,- United States, residing at.

Memphis, in the county of Shelby and `State of Tennessee, have inventednew and useful Improvements in Oil-Presses, of which the following is alspecification.

This invention relates tooil pressesy and. it.

consists in the, novel features hereinafter, described and claimed.`

y An object of the invention is to provide an improvedystructureoverthose shown in my,y earl-ierPatents'No. 11,061,837., issued May 13,y1913, Aand 1,081,905, issuedDecember-.1-6,

1913, and over the structure shown in my ypend-ingl application Sen No88,903.

-In the present. structure thepresscomprises top -andbottom blocksconnected vtogether by means of ner and provided with -aV plunger orfollower adapted -tobel actuated; by liquid, in the usual manner.Columnsare connected at. their ends with the top and bottom blocks andcompression bars are provided with guides adapted to move. along jthesai-d columns.

Some of thesaid bars areprovided atlth'eir upper vsideswith flangeshaving recesses adapted ato' receivevha-ir mats and vdrain perforations;or openings and plates are slidably mounted with relation to each set ofbars. y Lever mechanisms arev 'ofpferaitively'f;` cnnected'with some ofthe upper plates and also operatively connected withV the lower` pl'ate`wherebyfthefsaid lower plate may be moved in an upward direction at afaster rate of speed than the upper plate in consequence of beingsubjected to pressure from the plunger. The bars are provided withsuitable grooves whereby the oil which is squeezed from the lmateriallocated between the sets of bars mav drain and drip upon the uppersurface of the plunger.

In the accompanying drawings Figure 1 is an end elevation of the presswith parts in section showing the kplunger in its lowest position;

Fig. 2 is a similar view showing the plunger in an elevated position;

Fig. 3 is a fragmentary side elevation of the press viewing the. same ata right angle to the illustration shown in Fig. l;

Fig. 4L is afragmentary horizontal sec-l tional view of the press cut onthe line dof Fig. 1.;

bolts in the usualman--4 pass through the saidflan ges and` communicate1 with the said` recesses.l The said barsare-arranged in sets Fig. 5 isa detailed sectional viewthrough the intermediate portion of a set bars'used: in the press.k

Y The,-presscomprisesa top 'or head block 1 and-a bottom .blockQccnnected together by means of bolts 3Y in the usual manner. plunger 4is inovably mounted abovethe bottom 'block2 and may be actuated by oilor any suitable liquid under pressure in the usual manner. Columns 5 aresecured 'at their ends to the top and bottoni blocks.-

Bars 6 are arranged in sets and the outer bars of each set areprovidedat their edges with guides 7 which slidably receive the colf' umns 5.vThe bars G are provided with grooves-8 whereby; the liquid which Vissqueezed from the material placed between the -sets ofbars may drainfrom thesame. A filler 10 is mounted at the lower surface ofy the top oryhead block 1 and is adaptedtocooperate with the upper set ofbars 6.y

The outer bars G of eachk set areprovided at `their upper sides withflanges 11 havingy recesses 9 adapted to receive hair mats 12.The-flanges are further provided withopen-v ingsy lwhich V,communicateat their inner ends with the recesses 9 and serve Ias-means whereby thefoil' or liquid mayV drain from between the sets .of bars. y

Hangers 15 are provided at their upper ends with slots 16 which receivebolts 17 attached to the edges 'of the top or head block 1. The saidhangers are attached at. their lower ends to the `outer bars G oftheupper set of bars.

Plates L0 areslidablyfmonnted atcthe .ends

of each set of bars G. The said plates are provided with flanges Q1having slots 9.2 which receive pins 23 carried by the outer bars 6 ofeach set of bars except the lowest set. The plates 20 except the lowestplates are provided with legs Qd and the legs of the upper plates areattached to the outer bars 6 of the next lower set of bars. T he plates20 are further provided with openings 25. The legs of the plates Q0adjacent the ends of the third set of bars 6 from the bottom of thepress are provided with extensions 20 which are pivoted to the outerends of levers 2 fulcrumed at the ends of the outer bars 6 of the lowestset of bars. The inner ends of the levers Q7 are pivoted to the endportions of the lowest plate '20. As illustrated in Figs. 1 and 2, thepivotal connections between the levers 2 7 and the lowest plate 20 andthe leg extensions 26 are .sor

placed'between the adjacent sets of bars 6 and the plunger 4 is causedto move in an 1 Yupwardv direction whereby the lower boxes approach theupper boxes successivelyfas the weight or support of the'boxes and mealor Y contents is transferred from the pins 23to a pressure on the lowerbox` orplunger; This process continues until all of tlieweight of theboxes and contents has been removed from the pins 17 at which time thecontin-` uation of the rise ofthe plunger 4 takes up tlieiveiglit of thehead block and then puts tension in theY bolts 3. It is during themovement of the plunger 4 before the entire weight is rremoved fromtliepins 17 that the chief and important motion of the end platesv-QO'takes place. This pressure causes the oil to ooze from the said'material andthe oil drainsfrom the bars througli'the grooves 8 and theopenings 13 and rims down into the upper portion of the plunger 4inthe'usualV Y manner. As 'the lowest set yof bars 6 of the series ofsets is forcedv up closer toward the lnext set above the leg extensionsv26 Vcause the levers 27' toswing on their pivotal connection withftliebars whereby'the lowestplatesrQOai-e moved in an upward direction atafaster rate of speed than the upper plates 20 andV this confines thematerial between the two lower sets of bars aiide'ffectu- `ally squeezesor presses Vall of the oil outI 0f the same. f

l'From the foregoing descriptionv taken in,

conjunction with the accompanying drawing, it will be seen that van oilpress oi simpleand durable structure is provided and that the same maybe used econoniically'toV advantage'for squeezing the oil frominaterial, as for instance, cotton seedl and that coplas ot this patentmay be obtained for the #said oil isi-'permitted to draiiilfrom theYbars intothe plunger where it is collected vand maybe reniovedfrom thesame at desired intervals.v 1
